What this Income Tax Calculator India does
This calculator helps you estimate income tax in India by comparing the old and new tax regimes. You can enter your annual income, standard deduction, 80C, 80D, home loan interest and other eligible deductions. For business owners and salaried users managing GST or seller finance, this page connects naturally with the GST Calculator, Profit Margin Calculator and Percentage Calculator.
New regime calculations here use the FY 2025-26 / AY 2026-27 style slab structure and 87A rebate logic. The Indian Income Tax Department page lists AY 2026-27 new regime slabs starting with nil up to ₹4 lakh and higher slabs up to 30% above ₹24 lakh. The tool includes 4% health and education cess and gives a clean estimate for normal income.
How to use
Add your gross annual income before tax and choose taxpayer type.
Use standard deduction, 80C, 80D, home loan interest and other old regime deductions.
Click calculate to see old vs new regime and download CSV reports.
Example
Suppose your annual salary is ₹12,00,000. Under the new regime, after a ₹75,000 standard deduction, taxable income becomes ₹11,25,000. Because the new regime rebate benefit applies up to ₹12 lakh taxable income, the estimated tax can become zero for normal income. Under the old regime, your result depends heavily on 80C, 80D, home loan interest and other deductions.
